Product Description:

A manhole cover is a removable plate forming the lid over the opening of a manhole, to prevent anyone or anything from falling in, and to keep out unauthorized persons and material.

Manhole covers are often made out of cast iron, concrete or a combination of the two. This makes them inexpensive, strong, and heavy, usually weighing more than 50 kilograms (110 lb). The weight helps to keep them in place when traffic passes over them, and makes it difficult for unauthorised people not having suitable tools to remove them.

A manhole cover sits on metal base, with a smaller inset rim which fits the cover. The base and cover are sometimes called "castings", because they are usually made by a casting process, typically sand-casting techniques.

4,Manhole Cover Specifications:

1) Production informationManhole cover are manufactured for construction and public use. Manhole cover shall be smooth and free sand holes, blow holes, distortion or any other defects

A. It’s likely that your cover is quite old and in imperial measurements which are no longer manufactured. However, we can offer bespoke solutions with manhole covers made to the specification you require.

Q. The project I’m working on requires a manhole cover with a quality finish, what’s available?

A. Naturally, galvanised steel of black polypropylene aren’t always ideal, and so we offer brass or stainless steel edging, as well as complete stainless steel covers.

Q. Odours are coming through where I have installed my manhole cover, why?

A. Your cover must be sealed and locked, or neoprene sealed, so you would require a T-Range Cover, or if you require a solid top, a selection of the PC range (e.g. PC2BG3, PC6CG3, not PC2BG) are suitable.

Q. I need access through my manhole cover on a regular basis, is this possible?

A. Yes, the majority of covers have built-in lifting keys, and for those that don’t we also supply lifting keys. However, the best way to obtain easy access is to have a bespoke, hinged manhole cover.

Q:Easy Help: Transition Metals?

Id have to say Technical Death Metal because i love the intricacies of the music guitar and drums. a close second would be brutal death metal for the speed and power. Since i got into metal when i was about 12 id say my tastes have changed drastically but over the last 4 or 5 years ive pretty much stayed stuck on tech death. Favorite bands: Necrophagist Obscura Augury The Faceless Neuraxis Viraemia

Dude you have to expand your thoughts if you think pointedly about anything art, life, and general other things you miss out on the greatest things. I love metal its my favorite style of music, but I'm willing to listen to anything.......exept christian music, country, and rap(rap does have a good beat sometimes though). Metal is a great way for me to get into any book I'm currently reading(that's hardcore) and go with the flow man.

i love metal. I live, breathe, and dream metal. me personally though i like the good old fashion old school death metal like death, old school. dying fetus, Nile immolation, krisiun, carcass. that stuff. but i still love progressive death metal, folk metal, original technical death metal not this faceless ****. I like heavy metal and melodic death metal as well. sorry if my answer is scattered im a little tired. lol
